GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 700,205, dated May 20, 1902. Application filed February 19, 1901. Renewed April 17, 1902. Serial No. 108,433. (No model.)

To all whom, it may concern.- gas, the gas passing upward through said pas- 5 Be it known that we, PETER KELLER and sage B to the top of said projection C, thence PHILIPP SEILER, citizens of the United States, downward through the spaces H between the residing at Chicago, in the county of Cook and side walls of said cap D and said projection State of Illinois, have invented certain new C, thence upward through the space I beand useful Improvements in Gas-Burners; tween said cap D and said casing G, thence and we do hereby declare the following to be between the upper surface of said cap D and a full, clear, and exact description of the insaid shoulder E, thence through the outlet J. vention, such as will enable others skilled in As the gas -pressure increases said cap is [O the art to which it appertains to make and use raised more and more, thus decreasing the the same.- space' between the upper surface of same and Our invention relates to an improvement in said shoulder E until said cap is pressed gas-pressure regulators, the object being to against said shoulder, when the gas-passage provide a regulator which will automatically is reduced to a very small area, consisting r5 preserve a uniform pressure at the delivery only of the spaces between the corrugations end of same regardless of any variations of in the upper wall of said cap D and said shoulgas-pressure at the inlet end; and it consists der E. Said projection C is provided with a in the features of construction and combinagroove K in its outer surface at its lower end, tions of parts hereinafter fully described and forming the shoulder L, and said cap D is pro- 20 claimed. vided with inwardly projecting points M,

In the accompanying drawings, illustrating adapted as said cap D is raised to strike said our invention, Figure l is a vertical central shoulder L, and thus prevent the removal of section ofaregulator madeinaceordance with said cap D. This is of use only'when said our invention. Fig. 2 is a horizontal section casing G is removed in preventing said cap D 2 5 on line 2 2, Fig. 1. Fig. 3 is a vertical cenvin becoming separated from said member A tral section of a gas-burner provided witha and being lost. regulator made in accordance with our inven In Fig. 3 we have shown a'modification of tion. said regulator adapted to be inserted in a In said drawings, A represents a base procommon gas=pillar N. The lower end of said 30 vided witha central passage B, through which member A is externally screw-threaded and the gas is adapted to pass. In Fig. 1 said pasis adapted to be'screwed into the lower end sage B is enlarged at the lower end and is of said pillarN by means of the screw-driver provided with an internal screw-thread adaptslot 0 in its lower end. In this case the coring said member A to be connected to a pipe rugated cap D is adapted to' strikeor press 5 or other supply of gas. Said member A is against the wire screen lflwhich is ordinarily provided with a central projection C on its placed in gas-pillars in place of the shoulder upper end, upon which is loosely mounted a E, as in Fig. 1. corrugated shell or cap D, which is adapted We claim as our invention to be raised by the gas as it passes upward A device for regulating the flow of gas com- 40 through said passage B. The upward moveprising a base provided with an upwardly-exment of said cap D is limited by the internal tending nipple, an exterior groove in said nipgo shoulder E, formed on the casing G, which is ple adjacent its lower end, a central opening adapted to be secured to the upper end of in said base and through said nipple, a fluted said member A. As the upper surface of said cylindrical cap adapted to fit loosely over said 5 cap D comes in contact with said shoulder E nipple, prongs on the lower end of said cap the flow of gas is limited to the amount which extending into-said groove, a casing adapted 9 5 can pass through the spaces between the corto be mounted on said base and over said cap,- rugations in said cap and said shoulder E. and a central opening in the upper wall of In operation the said cap D is raised by the said casing of less diameter than said cap,

being entirely shut off at any time, snbstan the latter being adapted to be raised by ex- I In testimony whereof we aflix our signacessive pressure of gas and strike the upper tnres in presence of two witnesses.
